Photo-storage and Framing Materials Evaluations
(ISO 18902)

NOTE: Results expire! Results are valid for the specific lot of product tested until any date and for subsequent lots for one year.

Major Revision to ISO 18902 Imaging materials — Processed imaging materials — Albums, framing and storage materials

This standard was created to help users select photo-safe enclosures and to provide guidance to manufacturers on how to make photo-safe products. In 2011, the ISO committee on Physical Properties and Permanence of Imaging Materials initiated a major revision of ISO 18902:2007. This revision, published in 2013, made the document more user-friendly for both manufacturers and cultural institutions while maintaining the quality of output from the requirements. The key improvements are discussed in the article below and include: changes in scope, changes in terms and definitions, the elimination of redundant tests, the elimination of unspecified or unverifiable requirements, the elimination of irrelevant, intermittent, or incomplete information, and the development of a reporting method.

What is photo-safe?

A photo-safe material is one that will not cause damage or accelerate the natural aging of photographic prints or films or digitally printed images. ISO 18902 Imaging materials — Processed imaging materials — Albums, framing and storage materials contains all the requirements for a material to be considered photo-safe. Requirements vary depending on the type of material in question (paper, plastic, adhesive, etc.). Only materials that meet all the specifications of this International Standard can be considered photo-safe. Materials that only pass the pH requirements or only pass the PAT are not necessarily photo-safe due to other factors that may be harmful. For a complete understanding of photo-safe specifications you can purchase the standard at www.iso.org.

Why should I test?

Testing provides consumers and manufacturers of imaging and photo storage and display materials with unbiased, data-driven answers to questions of print stability, relative longevity and photo safety.
